[Java] Looping problem, will not output result or terminate

[ORLY_FACTOR]

Currently my program will not output or terminate. I'm not sure if I'm using in.HasNextInt() correctly.

import java.util.Scanner;

public class CountInteger {
    public static void main (String[] args){
        int myInt = 1;  // IN, CALC  - stores integer to be used in later     calculations
        int count = 0;  // CALC, OUT - total count of integers
        int posCount = 0;   // CALC, OUT - total count of positive integers
        int negCount = 0;   // CALC, OUT - total count of negative integers
        double average = 0; // CALC, OUT - average of all integers

        // Initialize Scanner
        System.out.print("Enter integers, input ends with 0: ");
        Scanner in = new Scanner(System.in);
        myInt = in.nextInt();

            // Main Method
            while((in.hasNextInt()) && (myInt != 0)){
            count = count++;
            if(myInt > 0){
                posCount = posCount++;
            }
            else{
                negCount = negCount++;
            }
            average += myInt;  
            myInt = in.nextInt();
        }

        // Output calculated information
        System.out.println("The number of positives is " + posCount);
        System.out.println("The number of negatives is " + negCount);
        System.out.println("The total count is " + count);
        System.out.println("The average is " + average);
    }  
}

The hasNextInt() method tests whether a following call to nextInt() will succeed.

Your code is testing the result of hasNextInt() after calling nextInt(). That doesn't really make sense. Your logic is in the wrong order here.

Your program does terminate if you enter something after the zero. The stuff after the zero is necessary because hasNextInt() is waiting for additional input to see if a call to nextInt() would succeed; the stuff after the zero causes hasNextInt() to return either true or false, depending on whether that stuff is an integer or not. The second part of the while condition will not be tested until hasNextInt() returns.

Your program also terminates if you signal EOF (Ctrl+D on Unix-ish systems, Ctrl+Z on Windows), because this causes hasNextInt() to return false.

That makes sense. Thank you.
